4 Pack Flea Collar for Cats, Cat Flea and Tick Collar Glow in Dark, 8 Months Prevention Cat Flea and Tick Treatment, Waterproof Adjustable Cat Flea Collar, Tick and Flea Collar for Kitten Cat, Pink

I like these better than the TriOak collars because these ones won't come off as easily. With any natural flea collar products, it can take between a week and a week and a half for them to become fully effective. If you're worried about an infestation, supplement with Capstar for the first week. They look and smell great too, the glow is a very nice feature.

This product does not work well. My cats have had them on for 4 days and they are scratching worse today.

I have 2 cats that spend all day outside so I wanted something from fleas and ticks. This works great. At first the cats did not like them but I kept at it and they got used to it. They do what they are supposed to and I don't have to worry about fleas or ticks coming in my house with the cats.

Noneffective

They come individually packaged which is awesome. If you don't use them all right away, they will not go bad. I got both colors for my different gender cats and these things GLOW. So far they are great and they smell good, easy to assemble and cut.

It works and it's a pretty blue.

This smelled nice and was soft and pliable, for comfort on their necks. I like the fact that they glow in the dark, so I can see where my cats are in the dark. This didn’t seem to help get rid of existing fleas, so had to try another method. Hopefully this will help keep fleas away now that I have had to treat them with an oral flea medicine.

These are the worst flea collars I have ever bought, my animals still have fleas, I have sprayed my yard and house and then bought these flea collars for my indoor cats. Won't buy again.
